Race Website


This race is organised by Trionium who also organise many other great races such as the Greensand half and full marathon. This race fills up over a month in advance so enter early if you would like to take part. There's free use of a swimming pool and even a delicious free cooked breakfast waiting for you at the end!

The Course

This off-road route is simple - from Dorking to the top of the highest point in south eastern England (Leith Hill - ouch) and back. The terrain is a mixed bag of 45% very uneven hard tracks, 45% sandy or muddy paths, 5% grass and 5% on tarmac. If it is wet then it will be very muddy - time to enter and hope it rains!
